WALTER L. MITCHELL, 0F PICAYUNE, MISSISSIPPI.

RAIL-TIE.

To all whom it may concern:

Be it known that I, WALTER L. MITCHELL, a 'citizen of the United States, residing at Picayune, in the county of Pearl River and State of Mississippi, have invented certain new and useful Improvements in Rail-Ties,

of which the following is a specification,

This invention relates to rail ties, and more particularly to an improved rail fastoning structure.

The primary object of the invention is to provide a rail fastening wherein the driving spike and other similar fastening devices will be eliminated and to substitute therefor, 'a rail clamping structure which is so applied as to require the least possible number of connecting bolts.

The invention also contemplates the provision ofmeans, whereby the rail clamping structure will be securely held against further movement when once applied, the said means being in form of a locking bolt so constructed as to prevent its accidental removal.

Another important characteristic of the invention, resides in the novel manner in which the rail clamps are received by the tie, the same being so positioned as to prevent lateral movement thereof, further, to

afford an effective bracing means.

The invention also anns to provide a tie of the character described, which is extremely simple in. construction, thus reducing the cost of manufacture to a minimum and one which will be strong and durable in use and, finally, highly efiicient for the purpose for which it is designed.

All of the foregoing, together with additional advantageous details and arrangements of parts of the preferred embodiment of ,my invention will be clear from the specific description hereinafter contained, when read in connection with the accompanying drawings forming part thereof, wherein said embodiment of the invention is illustrated for the purpose of facilitating a full understanding of the presentimprovements.

In the drawings Figure l is a perspective view with the various parts of the construction assembled; Fig. 2 is a perspective with the rail clamps removed;

Fig. 3 is a longitudinal section of the device;

Fig. 4 is a detail plan view partly in section showing the locking bolt as first applied;

drawings, wherein like reference charac-' ters designate like or corresponding parts throughout the several views thereof, the invention may be said to comprise a base portion 1, having arranged thereupon, preferably centrally thereof, a plurality of inclined upstanding flanges 2, 8, and 4 respectively. The central. or middle inclined flange 3 has formed adjacent its enlarged. extremity, a rail receiving and supporting chair 5, which chair is pro vided with a rail supporting portion as at 6, the same being of a length to conform to the width of the base portion 1, while its under face is tapered as at 7 and merges with said base portion 1 as at 8, thus, allowing the same to be rigidly supported. The rail supporting portion 6, has arranged adjacent its outer extremity, an offset laterally extending extension 9, and has arranged' means whereby'the web of the rail may be.

also braced, at a point, adjacent its base portion. flange has arranged thereupon, intermediate its ends, an enlargement 12, which enlargement is so constructed as to afford substantially beveled or inclined bearing shoulders 13, the purpose of which shall be hereinafter more fullydescribed, while, arranged in close proximity to said enlargement is an L-shaped slot 14:. Positioned adjacent the smaller extremity of flange 3, is a second rail receiving and supporting chair 15, which chair is constructed in exact ac-- cordance with the chair 5, the rear end thereof being supported by the flange a. It may be stated that the oflset portion 9 of the rail receiving and supporting chair 5 is, in turn, engaged and supported or braced The middle tapered or inclinedvantage in Fig. 2 of the drawings, while,

' ing having laterally extended flanges 21Iand 1e ondary bracing and supporting means.

inan effort to reduce cost of construction, and, further to lighten thesame, I extend longitudinally, of the upstanding flanges, an opening or bore as at 19.

Referring now to the rail clamping constructlon, the clamping member 20, compris- 1 ing a substantially inverted U-shaped houshaving arrangedtupon one of its extremities,

a rail'receivinp; and supporting, chair 22, so

constructed as to be similar to the chair L15, the same being provided with a supportmg portion 23, which portion is received upon the oflset portion 9 and. abuts thev shoulder formed by the offset connection. of the portion 9 with therail supporting portion 6. A notched or recessed seat,

similar vto the recessed portion 10, is arranged upon the outer or free extremity of the rail. supporting portion 23, so positioned intermediate the ends thereof as to readily aline with the recessed portion 10. An inclined supporting leg 24, is formed upon the chair 22 and engages with the laterally extended flanges 21', thus serving as a secis to be also noted, that the sides of the clamping member 20 are flared outwardly, this being due to the tapered construction of the walls, which serve "to reinforce the same. The outer extremity-of the clamping member 20 is beveled as'at 25 and when ap- "plied to the flange, the said beveled portion positioned as to, when applied over the flange. 3, aline with the L-shaped slot l t.

The iocking bolt, designated in its entirety, as at 26 is adapted to be passed through the alined openings and the L-shaped slot 14:, thus, securing the same in the flange Attention is directed to the that the said alined openings in the clamping: member 20 are oppositely disposed, that is to say, one of the openings is substantially rectangular in shape while the remaining opening, is rectangular in shape, but is so disposed as to have the longer sides thereof, horizontally disposed. The locking bolt includes a head portion 27 and a threaded shank 28, the said shank having; arranged thereupon, adjacent the head 2?, a horizontally disposed key portion 29 and a key portion 30, the latter of which is spaced from the former and has its longitudinal axis at right angles to that of the portion 29. When inserting a key in the aforesaid openings, the portion 30 is turned so as to be admitted by the horizontal opening, in the clamping member 20 and is then forcediforwardly, until the said portion '30 engages with the opposite side of the clamping member 20, whereupon, the locking member is turned, allowing key 30 to be received by the vertically arranged portion of the h-shaped slot 14. When in this position, the key can be'again forced forwardly, the portion 30 engaging the vertically disposed opening in the clamp 20 while the portion 29 engages with the horizontal opening as -arranged in the clamping member 20. Alocking nut 31 is then turned into engagement with the threaded shank 28, securely holding' the bolt in position. A second clamping member 32 is receivable upon the flange 2, this clamping member being constructed in accordance with the clamping member 20, which is constructed so that the .U- shaped housing" portion thereof is of less length than that portion as arranged upon the clamping member 20. Therefore, it is thought that the description of the clamping member 20 will permit a full understanding of this particular construction.

To provide for means, whereby longitudi- ,nal movement of the rails 33 may be prevented, 1 form upon the lower face of the base portion, a depending lug 34, this lug, being received in the seat afforded by the notched or recessed portion 10.

While I have herein disclosed the specific embodiment of the invention, it will be apparent to persons skilled in the art, that the invention 'is capable of embodiment in other forms and devices differing in detail and arrangement from thatshown, as may be in keeping with the hereto appended claims.
